baby looking small- confused please help

So I'm 10 weeks pregnant and today the doctor could not find HR, so she did a quick US and found the baby and HR and she said the baby looked great but more like 8 weeks to her. I'm very confused because:
1. I recorded the date of my last period- first day
2. I got a strong + pregnancy test at ~14DPO. Cannot exactly pinpoint O but according to my mucous it was right on.
3. At my 5 weeks appt, my HCG was in the 6000's and progesterone 19.

In my conclusion, if i am 2 weeks behind, I wouldn't have got my + pregnancy test so fast and my numbers would have been lower at my first appt. I'm a little concerned now as to why the baby is looking so small :-(

Did she measure? Or just go by what she thought it looked like? With DS we had an ultrasound done at 10w5d and this time we had one on the same day. They look totally different even though its the same day and the babies both measured right on....

I actually got my positive more around 7-8 dpo, and I used OPK so I'm sure about the day I ovulated. And mucous isn't a good indicator because you can start getting up to 5-7days before you actually ovulate. And mine was gone when I got my +OPK! So it is possible to be off on your dates, I would say hearing a strong heartbeat is a good sign! Good luck and I hope your little bean keeps growing!

Same happened with me, she said I looked 2 weeks smaller so I had an ultrasound and they said my new due date was 10 days later than what I thought. I am positive of my lmp date so I guess I just ovulated later, but that also means I got a positive test super early, I thought at 4 weeks 3 days, but this means I was barely 3 weeks and tested positive

I'm in the same boat. By new due date I got a positive pregnancy test while ovulating, because it would put me at 2 weeks pregnant.
It didn't make sense to me, or really to my midwife, but she said by. Crown to rump measurements the ultrasound was accurate. I'm trying not to worry about it too much, midwife just said we continue to monitor as we get closer to my various due dates. :)

Even with ovulation dates confirmed by clearblue fertility monitor and temping, both of my babies measured 2 days ahead of my O dates very early on (6 and 8 weeks), and even farther ahead by 12 weeks (4 and 6 days ahead). So babies do grow at different rates. I also got a BFP at 8 dpo with DS. When do you think you O'd by CM?

When I got my ultrasound I thought I was 10 weeks but I measured to be 9. I guess it was possible but to be honest, I still think I'm farther along. I'm 12 weeks now (after being pushed back a week) but I'm eager to see my doctor and see how I've progressed. Sometimes they will change how far along you are later if your baby is measuring bigger.
